SUPPORT FOR GRAIN-CLEANERS.

Specification of Letters Patent.

Patented June 13, 1911.

Application filed July 28, 1910. Serial No. 574,318.

To all whom it may concern:

Be it known that I, HENRY J. MIoHAnL- SEN, a citizen of the UnitedStates, residing at Moscow, in the county of Latah and State of Idaho,have invented certain new and useful Improvements in Supports for Grain-Gleaners, of which the following is a specification.

In combined harvesters and threshers means are generally provided forcleaning the grain after its removal from the straw, a separatemechanism being provided therefor. The operation of this grain-cleaningmechanism is detrimentally affected or even rendered inoperative by thesaid apparatus being tilted, as by reason of the implement over unevenor sloping ground. In machines of this character, the grain-cleaningapparatus is rigidly mounted upon the frame of the same, whereby whensaid frame is tilted the grain-cleaning apparatus is also tilted or thecleaning mechanism is adjustably mounted upon the main frame of thesame, and manually operated means are pro-- vided for keeping it in itsproper position. Both of these methods are unsatisfactory. So far as Iam aware, no simple and effective means have been provided for retainingthe grain-cleaning mechanism in its proper position, when the frame ofthe harvester is tilted.

An important object of my invention is to provide means for mounting agraincleaning apparatus upon the main frame of a combined harvester andthresher or the like, which will permit said mechanism to remain in itsproper, normal position, independently of any change in the angularposition assumed by the main frame.

A further object of this invention is to provide connecting meansbetween the grain cleaning apparatus and the main frame of the combinedharvester and thresher, which is in effect a universal joint, togetherwith simple and automatic means for retaining thegrain-cleaningapparatus in its proper osition.

Other objects and advantages of this invention will be apparenthereinafter.

In the accompanying drawings, forming a part of this specification, andin which like numerals are employed to designate like parts, throughoutthe same, Figure 1 is a side view of the grain-cleaning apparatus,showing my improved means for connecting travel of the V the same withthe main frame of a combined harvester and thresher, Fig. 2 is a centralvertical section through the connecting means, Fig. 8 is a top plan viewof the socket-member of the connecting means, Fig. 4 is an enlargedsectional view through the socket-member, Fig. 5 is an enlarged detailsection through the socket-member, and showing one of the ball-socketsformed therein, and Fig. 6 is an enlarged elevation of the extensibleshaft.

In the drawings, wherein is illustrated a preferred embodiment of myinvention, the numeral 1 designates a grain-cleaning apparatus, as awhole, which may be of any well known or preferred type. Thisgrain-cleaning apparatus will not be described, in detail, as no claimwill be made to the same, per 86. The mechanism of this graincleaningapparatus is mounted within its casing 2. This mechanism is actuated bymeans of a shaft 3, having a bevel-gear 4 rigidly mounted upon the same,as shown. A com bined flexible and extensible shaft 5 is provided,comprising a tubular central portion 6, within which is slidably mountedshafts 7, as shown. The tubular portion 6 is provided with elongatedslots 8 near its ends,

for the reception of pins 9 having rigid engagement with the shafts 7. W

From the description of the above referred to parts, it is obvious thatthe shafts 7 may move longitudinally within the tubular portion 6, butcannot rotate therein. The shafts 7 have universal connection withshafts 10, as shown at 11. The upper shaft 7 is journaled throughbrackets 12, which are bolted to one side of the casing 2. The shaft 10has a bevel-gear 13 rigidly connected therewith, and in engagement withthe bevel-gear 4. The other shaft 10 is journaled through a bracket 14,rigidly mounted upon a main frame 15 of a combined harvester andthresher, or the like. The lower shaft 10 is provided with a bevel-gear16, which engages a bevel-gear 17 suitably mounted upon the main frame15. The bevel-gear 17 is mounted upon a shaft 17 driven by a suitablemotor (not shown) which is disposed upon the main frame 15. It isobvious that the rotation of the bevel-gear 17 will be imparted to thebevel-gear 4, by mean of the combined extensible and flexible shaft,above described.

Rigidly mounted upon the main frame:

15, is a socket member 18, comprising an annular body portion 19 havinglegs 20 can ried thereon, and preferably cast integral therewith. Thelegs are suitably bolted to the main framel5, as shown at 21. Adapted tofit within the socket-member 18, is a hollow ball or substantiallyhemispherical member 22, having its material bent outwardly for formingcircumferential flanges, or ears 23, which are bolted to the bottom 24of the casing 2, as shown at 25. The annular body portion 19, isprovided upon its inner surface with a plurality of openings 26, forrotatably holding balls 27. The openings 26 are preferably arranged inspaced groups of four, as shown, although I do not restrict myself tothis specific arrangement alone. From the description of the abovereferred to parts, it will be obvious that the socket-member 18 is freeto move about the ball-member 22. In order that the grain-cleaningapparatus 1 may be retained in its requisite position, when the mainframe 15 and socket-member 18 are tilted, a weight 28 is provided,having rigid connection with a vertically disposed shaft 29, which ismember 22, at the point which it is desired shall occupy the lowermostposition.

In the use of the grain-cleaning apparatus, it is actuated by theextensible and flexible shaft 5, which, as above stated is not affectedby the relative movements of the grain-cleaning apparatus and main frame15. When the main frame 15 is tilted, the weight 28 will prevent theballmember 22 from partaking of this tilting movement, whereby thegrain-cleaning aprigidly connected with the ball- I paratus is retainedin its requisite position. It is thus seen that I have provided meansfor retaining the grain-cleaning apparatus in its proper position, whichis simple in construction and automatic in operation.

It is to be understood that the form of my invention herewith shown anddescribed, is a preferred example of the same, and that numerous changesin the size, shape and arrangement of parts may be resorted to with outdeparting from the spirit of my invention or the scope of the subjoinedclaim.

Having thus fully described my invention, what I claim as new and desireto secure by Letters Patent, is

In apparatus of the character described,

the combination with a supporting st-ruc-.

ture, of a socket-member mounted upon the same, a ball-member foroperation within the socket-member, grain-cleaning appa- ,ratus mountedupon said ball-member, a weight disposed below said ball-member, i meansrigidly connecting said weight and ball-member, driving mechanismmounted upon the supporting structure, driven mechanism mounted upon thegrain-cleaning apparatus, and self adjusting means for forming anoperative connection between normally passing substantially through theI axis of rotation of said ball-member.

g In testimony whereof I afliX my signature in presence of twowitnesses.
